　また、ヒューズブラケット４０に設けられるユニット支持部４１は、バッテリ直付け型ヒューズユニット３０のターミナル接続部３１の両側を摺動可能に保持する一対の第１ガイド溝４１１を有している。そこで、バッテリ直付け型ヒューズユニット３０のターミナル接続部３１自体には、特別な加工をせずとも、バッテリ直付け型ヒューズユニット３０をバッテリ１０の側面１６と直交する方向に移動可能に支持することができる。そのため、既存のバッテリ直付け型ヒューズユニット３０に対しても、干渉防止を図ることができる。 The unit support portion 41 provided in the fuse bracket 40 has a pair of first guide grooves 411 that slidably hold both sides of the terminal connection portion 31 of the battery direct attachment type fuse unit 30. Therefore, the terminal connection portion 31 of the battery direct-attachable fuse unit 30 is supported so that the battery direct-attachable fuse unit 30 can move in a direction orthogonal to the side surface 16 of the battery 10 without any special processing.
